Description

  The present invention relates to an information processing apparatus controlled using parameters for a plurality of setting items, and in particular, an information processing apparatus with improved operability when initializing individual setting items and initialization of the setting items Regarding the method.

  In various electronic devices for commercial and consumer use that are widely used today, the user can set various parameters for controlling electronic devices by entering arbitrary parameters using the numeric keypad. There are many.

  For example, there is an image switching device called a switcher as a kind of electronic equipment for broadcasting business. The switcher selects a video signal from a plurality of channel input video signals (video signals from a video camera, VTR, etc.), and transitions from one of the two selected video signals to the other video signal. This is a device that outputs a video signal with such an effect.

As such a switcher, for example, regarding an effect, a plurality of setting items including the following items (1) and (2) can be arbitrarily input with a numeric keypad on a GUI (graphical user interface) screen. What has become a product.
(1) Effect pattern
(2) Items related to the color of the border between two video signals to be transitioned

  The user can set these items arbitrarily and operate the switcher. However, there is a case where one wants to initialize one of the setting items afterwards (for example, to return the parameter to the initial value set at the factory). is there. For this reason, a switcher that can perform an operation for initializing individual setting items on the GUI screen has already been commercialized.

  FIG. 1 is a diagram showing such a GUI screen. A “Default Recall” button, which is a button for initialization, is provided at the upper right of the screen. A plurality of icons in which setting items are grouped are displayed in the main menu column in the center of the screen. Among the displayed icons, “Eff Ptn” is an icon related to the effect (1). “Color” is an icon related to the color of the boundary line in (2) above.

  The operation procedure for initializing individual setting items on the GUI screen is as follows. For example, when the user wants to initialize the border color setting, the user presses the icon “Color” on the main menu. Then, as shown in FIG. 2, on the lower side of the screen, three icons “Lum” representing three setting items for the border color, luminance (luminance), saturation (saturation), and hue (hue), respectively. , “Sat”, “Hue” are displayed.

  For example, when it is desired to initialize the luminance of the boundary line, after pressing the “Default Recall” button and then pressing the icon “Lum”, the parameter of the luminance value of the boundary line is returned to the initial value. Similarly, when the icon “Sat” is pressed after the “Default Recall” button is pressed, the saturation parameter of the border is reset to the initial value, and after the “Default Recall” button is pressed, the icon “Hue” When is pressed, the hue parameter of the boundary line is reset to the initial value.

  However, such an electronic device has a very large number of functions in addition to the functions shown in this specification, and even if the operator actually uses the device, all functions and operation methods are provided. It is difficult to get to know. For this reason, there is a demand for an electronic device that can easily find out how to operate a desired function without carefully reading the instruction manual.

  As a solution to this problem, a GUI screen as shown in this specification is provided, and a character string explaining functions on the screen, operation buttons (switches), states by various figures / character strings, etc. It is possible to guess the operation method just by viewing.

  By the way, in the attached drawings such as FIG. 1 and FIG. 2, only the part related to the feature of the present invention is drawn. However, since the actual GUI screen of these electronic devices controls many functions, Etc. are displayed. For this reason, even if a character string to be described is displayed, it may be difficult to find a desired icon or the like from a large number of displays.

  For this, there is a solution to make the screen hierarchical. That is, when an icon indicating a category desired to be operated is designated (pressed), a new screen (window) is displayed by a pop-up display, and an operation target is selected by focusing on only the pop-up display. It narrows down and saves you the trouble of searching for a user interface that is easy to use.

  In the prior art electronic device, the parameter is initialized by pressing the “Default Recall” button and then pressing the icon of the parameter. However, although the “Default Recall” button is always displayed on the screen, there is a problem that it is difficult to understand what is effective and in what order the screen is used.

  In addition, when a numerical value is input to a parameter (setting item), a method is provided in which a numeric keypad is displayed in a pop-up by performing an operation for instructing the corresponding parameter, and a numerical value is input to the numeric keypad to confirm. . Even if the operator is familiar with the operation of the numeric keypad input, it is difficult to guess the operation of the “Default Recall” button of the prior art, and there is a problem that it is necessary to learn separately.

  On the other hand, it is assumed that the user presses the icon “Eff Ptn” on the main menu in the GUI screen of FIG. Then, as shown in FIG. 3, an icon “Ptn No” representing the effect pattern is displayed at the bottom of the screen.

  However, with this switcher, there is no default setting for the effect pattern from the beginning (the effect that the user inputs the pattern number as a parameter is only executed, and the initial value of the pattern number does not exist). It is impossible.

  However, for the user, this is not apparent on this screen. For this reason, after pressing the “Default Recall” button, the icon “Ptn No” is pressed to assume that the effect pattern settings have been initialized, but in reality the effect pattern has not changed at all. Can occur.

  In this way, in the GUI screen for switcher initialization that has been commercialized in the past, among the plurality of setting items, distinction between items that have an initial setting state (initial values exist in parameters) and items that do not exist It is hard to say that the operability is good because there is a case where a useless operation is performed on an item for which there is no initial setting state.

  In the literature, a technique has already been proposed in which the operability is improved by changing the function of the same soft key in accordance with the transition of the electronic device from the default (initial) state to the next state. (For example, refer to Patent Document 1). However, this technique does not improve the operability when performing initialization, but conversely, improves the operability when gradually moving away from the initial state. There was no literature describing techniques for improving the operability during initialization in the range investigated.

JP-A-7-297891 (paragraph numbers 0011 to 0014, FIGS. 2 to 4)

In view of the above-described points, the present invention improves the operability when initializing individual setting items in an information processing apparatus controlled using parameters for a plurality of setting items, such as such a switcher. Is an issue.

In order to solve the above problem, an information processing apparatus according to the present invention is selected by a selection unit that selects a setting item for setting a parameter of an item from among a plurality of items by a user operation input, and the selection unit. If the setting item is an item for which an initial value exists in the parameter, an initialization icon is displayed on the display screen, and the setting item selected by the selection means is an item for which no initial value exists in the parameter If a display control unit that does not display an icon for initialization on the display screen, the user operation input, if the selection icon for initialization is commanded to return the parameters of the selected setting item to the initial value Initialization processing means.

In addition, the setting item initialization method according to the present invention is a setting item initialization method in an information processing apparatus controlled using parameters for a plurality of setting items. from the display a selection step of selecting the setting item setting parameters of the items, the setting item selected by the selection step, if an item is present the initial value to a parameter, the icon for the initialization on the display screen If the setting item selected in the selection step is an item that does not have an initial value in the parameter, the display control step that does not display the initialization icon on the display screen and the user input for initialization An initialization process step for returning the parameter of the selected setting item to the initial value when the selection of the icon is instructed.

According to the present invention, whether or not an initial value exists for each setting item when an initialization icon is displayed along with the display of the numeric keypad on which the user pays attention when inputting a parameter on the GUI screen. And the display of the initialization icon can be controlled. For this reason, the user can easily understand that the pressing of the initialization icon acts only on the setting item (parameter) currently being operated only by looking at this display. Regardless of how many displays are displayed on the GUI screen before the numeric keypad pops up, operations including initialization can be performed by gazing only at the numeric keypad display area during the numeric keypad operation. As a result, the user can easily find the initialization procedure for the setting item currently being input without searching on a wide GUI screen, so that it is easy to learn and the operability can be improved. It is done.

  Hereinafter, an example in which the present invention is applied to a broadcaster switcher will be specifically described with reference to the drawings. FIG. 4 is a block diagram showing an outline of the configuration of the switcher to which the present invention is applied. This switcher is composed of a switcher body 1 and a control panel 2.

  In the switcher body 1, an input selection circuit 3, an image composition circuit 4, an internal signal generation circuit 5 and a control unit 6 are provided. Further, the switcher body 1 receives a plurality of channels of video signals (for example, video signals from video cameras, VTRs, etc.) from input lines 7a to 7f.

  The input selection circuit 3 has a matrix-like selection switch group for connecting the input lines 7a to 7f to the input buses 3a and 3b, and selects video signals from one input line by the input buses 3a and 3b, respectively. it can. The two video signals selected by the input buses 3a and 3b are sent to the image synthesis circuit 4.

  The image composition circuit 4 is a circuit that applies an effect of causing the video signal output from the switcher body 1 to transition from one of the two video signals selected by the input selection circuit 3 to the other video signal. is there.

  The internal signal generation circuit 5 is a circuit that generates a video signal used for displaying a boundary line between two video signals when the image synthesis circuit 4 applies an effect. The internal signal generation circuit 5 generates the internal signal generation circuit 5. The video signal is also sent to the image composition circuit 4.

  The control unit 6 includes a microcomputer and a communication interface, and controls the entire switcher body 1 based on information transmitted from the control panel 2.

  The control panel 2 includes an operation unit 8, a GUI unit 9, and a control unit 10. Although not shown, the operation unit 8 includes various operation means for operating the switcher body 1 (operation buttons for selecting a video signal by the input selection circuit 3 and two images from the image composition circuit 4. Faders, levers, etc.) for manually adjusting the signal output ratio.

  The GUI unit 9 is for setting various items for operating the switcher body 1 before operating the operation unit 8 to operate the switcher body 1. The GUI unit 9 is configured by a liquid crystal display with a touch panel, and this setting is performed on a GUI screen displayed on the liquid crystal display.

  The control unit 10 includes a microcomputer and a communication interface, and transmits information indicating an operation result in the operation unit 8 and a setting result in the GUI unit 9 to the control unit 6 in the switcher body 1. .

The GUI unit 9 can arbitrarily input parameters for a plurality of setting items including the following items (1) to (3), for example, for effects.
(1) Effect pattern
(2) Items related to the color of the border between two video signals to be transitioned
(3) Appearance position and width of this boundary line

  FIG. 5 is a diagram illustrating patterns that can be set as the item (1). When a certain pattern number (integer value) is input as a parameter for the effect pattern, as illustrated in FIG. 5A, from the edge of the screen on which the current image (drawn in white) is displayed, Another image (drawn with diagonal lines) appears, the ratio of this other image gradually increases, and finally the pattern is set to completely switch to this other image.

  Further, when another pattern number is input as a parameter for the effect pattern, as illustrated in FIG. 5B, another screen number on the current image (drawn in a white background) is displayed. An image (drawn with diagonal lines) appears, the ratio of this other image gradually increases, and finally a pattern is set that completely switches to this other image.

  The item (2) includes the luminance, saturation, and boundary of the boundary lines of two video signals to be transitioned as illustrated in FIG. 5 (vertical lines in FIG. 5A and rhombic lines in FIG. 5B). This is an item for setting the hue (for example, setting it to bright and vivid blue or dark and turbid red), and set the brightness, saturation, and hue parameters to decimal values (2 decimal places are the lowest digit) The value is entered as

  The item (3) is an item for setting the appearance position and width of the boundary line as illustrated in FIG. FIG. 6 is a diagram illustrating the appearance position and width of a rhombus boundary line, taking the effect pattern of FIG. 5B as an example.

  Among these, FIG. 6A is a diagram illustrating the appearance position. In the left diagram, the diamond appearance position p is the center of the screen, and in the right diagram, the appearance position p is lower left than the screen center. It has become. As for the appearance position, the parameter representing the center of the screen is set to 0, the position parameter in the horizontal direction of the screen is input in the range of −4.00 to 4.00, and the parameter of the vertical position of the screen is set to −3. The input is in the range of 00 to 3.00.

  FIG. 6B is a diagram illustrating the result of setting the width. In the left diagram, the width of the rhombus boundary line bd is narrowed, and in the right diagram, the width of the border line bd is increased. Yes. The parameter of this width is also input as a decimal value (a numerical value with 2 digits after the decimal point as the lowest digit).

  Among these setting items (1) to (3), for the items (2) and (3), there are factory default values, and the initial values themselves are displayed on the GUI screen by the user. It is also possible to change. However, there is no initial value for item (1) (the effect that the user inputs the pattern number as a parameter is only executed, and the initial value of the pattern number does not exist).

  As described above, the setting items for the switcher main body 1 include items having an initial value and items not existing. The control unit 10 (FIG. 4) stores various setting items for the switcher body 1 by distinguishing between items having an initial value and items not having an initial value, as well as the current initial values (items) for the items having an initial value. Is the initial value set at the factory when the initial value is not changed, and is the initial value after the change when the user changes the initial value). If description is added about storage of initial values, this apparatus has a function of storing a value set by a user as a current initial value for each item. The user can set an initial value (User Default), and when it is canceled, the current initial value can be returned to the value set at the time of factory shipment (Factory Default). Such initial value setting can be easily realized using the GUI screen.

  FIG. 7 is a diagram showing a GUI screen displayed on the GUI unit 9 in order to input parameters for these setting items and to initialize individual setting items. A plurality of icons in which setting items are grouped are displayed in the main menu column in the center of the screen. Among the displayed icons, “Eff Ptn” is an icon related to the effect (1). “Color” is an icon related to the color of the boundary line in (2) above. “Position” is an icon related to the appearance position and width of the boundary line in (3) above. In the attached drawings including FIG. 7, only the display related to the feature of the present invention is drawn on the GUI screen, but many other characters, icons, etc. are displayed on the GUI screen of the actual device. The

  Assume that the user presses the icon “Color” on the main menu on the GUI screen. Then, as shown in FIG. 8, on the lower side of the screen, three icons “Lum” respectively representing three setting items regarding the color of the boundary line, luminance (luminance), saturation (saturation), and hue (hue). , “Sat”, “Hue” are displayed. In each of the icons “Lum”, “Sat”, and “Hue”, the current brightness, saturation, and hue parameter values are displayed as bar graphs and numerical values, respectively. As described above, there are initial values for the luminance, saturation, and hue of the boundary line.

  For example, when the user wants to initialize the setting for the brightness of the boundary line, the user presses the icon “Lum”. Then, under the control of the control unit 10 (FIG. 4), a pop-up screen as shown in FIG. 9 is displayed on the GUI unit 9 in a separate window from the screen of FIG.

  On this pop-up screen, a numeric keypad 21 is displayed and a “Default Recall” button 22 which is a button for initialization is displayed. In addition, a display field 23 in which a numerical value input with the numeric keypad 21 is displayed and a “Close” button 24 that is a button for closing the pop-up screen are also displayed. Since the “Default Recall” button 22 is displayed on this pop-up screen, the user can easily guess that the button 22 is a means for initializing the setting item “Lum” (luminance) currently focused on. it can. In addition, it is possible to easily and accurately confirm that the brightness of the boundary line is an item that can be initialized.

  When the user presses the “Default Recall” button 22 on the pop-up screen, the control unit 10 returns the boundary brightness parameter to the initial value, and the pop-up screen is closed. Although illustration is omitted, under the control of the control unit 10, the bar graph and the numerical value in the icon “Lum” on the screen of FIG. 8 change so as to represent the initial value.

  When the icon “Sat” is pressed on the screen of FIG. 8, the same pop-up screen as shown in FIG. 9 is displayed. Then, when the “Default Recall” button 22 is pressed, the control unit 10 returns the boundary saturation parameter to the initial value, and this pop-up screen is closed, and a bar graph and an icon “Sat” on the screen of FIG. The numerical value changes to represent the initial value.

  When the icon “Hue” is pressed on the screen of FIG. 8, the same pop-up screen as shown in FIG. 9 is displayed. When the “Default Recall” button 22 is pressed, the control unit 10 resets the hue parameter of the boundary line to the initial value, and this pop-up screen is closed, and the bar graph and numerical value in the icon “Hue” on the screen of FIG. Changes to represent the initial value.

  In addition, after the pop-up screen of FIG. 9 is displayed by pressing the icons “Lum”, “Sat”, or “Hue” on the screen of FIG. 8, any parameter can be set with the numeric keypad 21 instead of pressing the “Default Recall” button 22. When the “Enter” key is pressed and the “Enter” key is pressed, the control unit 10 sets the luminance, saturation, and hue of the boundary line according to the input result, and this pop-up screen is closed. Under the control of the control unit 10, the bar graphs and numerical values in the icons “Lum”, “Sat”, and “Hue” on the screen of FIG. 8 change so as to represent the values input by the numeric keypad 21.

  Further, after the pop-up screen of FIG. 9 is displayed, if the “Close” button 24 is pressed instead of pressing the “Default Recall” button 22, this pop-up screen is immediately closed.

  Assume that the user presses the icon “Eff Ptn” on the main menu on the GUI screen of FIG. Then, as shown in FIG. 10, an icon “Ptn No” representing an effect pattern (see FIG. 5) is displayed at the bottom of the screen. The currently set pattern number is displayed in the icon “Ptn No”. As described above, there is no initial value for this pattern number.

  Assume that the user presses this icon “Ptn No” to initialize the effect pattern. Then, under the control of the control unit 10, a pop-up screen as shown in FIG. 11 is displayed on the GUI unit 9 in a separate window from the screen of FIG.

  On this pop-up screen, the same numeric keypad 21, display field 23 and “Close” button 24 as the pop-up screen shown in FIG. 9 are displayed, but the “Default Recall” button like the pop-up screen in FIG. 9 is not displayed. Since the “Default Recall” button is not displayed on the pop-up screen, the user can easily and accurately confirm that the effect pattern is an item that cannot be initialized.

  After confirming that the effect pattern cannot be initialized in this manner, the user can immediately close the pop-up screen by pressing the “Close” button 24. Alternatively, as an alternative to initialization, the effect pattern can be immediately reset by the numeric keypad 21 (in this case, the icon “Ptn No” on the screen of FIG. 10 under the control of the control unit 10). (The pattern number in the figure changes to represent the value input with the numeric keypad 21.)

  Assume that the user presses the icon “Position” on the main menu on the GUI screen of FIG. Then, as shown in FIG. 12, on the lower side of the screen, three icons “H Pos” and “ “V Pos” and “Width” are displayed. In each of the icons “H Pos”, “V Pos”, and “Width”, the current horizontal position, vertical position, and width parameter values are displayed as bar graphs and numerical values, respectively. As described above, there are initial values for the appearance position and width of the boundary line.

  For example, the user presses the icon “H Pos” to initialize the setting of the appearance position in the left-right direction of the boundary line. Then, under the control of the control unit 10, a pop-up screen as shown in FIG. 13 is displayed on the GUI unit 9 in a separate window from the screen of FIG.

  This pop-up screen is exactly the same screen as shown in FIG. Since the “Default Recall” button 22 is displayed on the pop-up screen, the user can easily and accurately confirm that the appearance position of the boundary line in the horizontal direction is an item that can be initialized.

  When the user presses the “Default Recall” button 22 on this pop-up screen, the control unit 10 returns the parameter of the appearance position in the left-right direction of the boundary line to the initial value, and the pop-up screen is closed. Further, under the control of the control unit 10, the bar graph and the numerical value in the icon ““ H Pos ”on the screen of FIG. 12 change so as to represent the initial value.

  When the icon “V Pos” is pressed on the screen of FIG. 12, the same pop-up screen as shown in FIG. 13 is displayed. When the “Default Recall” button 22 is pressed, the control unit 10 resets the parameter of the appearance position in the vertical direction of the boundary line to the initial value, and this pop-up screen is closed, and the icon “ The bar graph and numerical value in “V Pos” change to represent the initial value.

  When the icon “Width” is pressed on the screen of FIG. 12, the same pop-up screen as shown in FIG. 13 is displayed. Then, when the “Default Recall” button 22 is pressed, the control unit 10 resets the boundary width parameter to the initial value, and this pop-up screen is closed, and the bar graph and numerical value in the icon “Width” of the screen of FIG. Changes to represent the initial value.

  Further, after the pop-up screen of FIG. 13 is displayed by pressing the icons “H Pos”, “V Pos”, or “Width” on the screen of FIG. 12, the numeric keypad 21 is used instead of pressing the “Default Recall” button 22. When the “Enter” key is pressed and the “Enter” key is pressed, the control unit 10 sets the left and right appearance positions and the vertical appearance position and width of the boundary line according to the input result, and the pop-up screen is closed. Then, under the control of the control unit 10, the bar graphs and numerical values in the icons “H Pos”, “V Pos”, and “Width” on the screen of FIG. 8 change so as to represent the values input by the numeric keypad 21. .

  When the “Close” button 24 is pressed instead of pressing the “Default Recall” button 22 after the pop-up screen of FIG. 13 is displayed, this pop-up screen is immediately closed.

  As described above, in this switcher, the user can determine whether or not the setting item designated to be initialized from the GUI screen of FIG. 7 is an item that can be initialized, whether or not the “Default Recall” button is displayed on the pop-up screen. (FIGS. 9, 11, and 13) can be confirmed easily and accurately, and the initialization operation (operation of the “Default Recall” button) can be performed only when the item is an item that can be initialized. . Accordingly, it is possible to prevent a useless operation from being performed on an item that cannot be initialized, and to improve operability when initializing individual setting items.

  In the above example, an item to be initialized is specified by pressing an icon such as “Lum”, “Sat”, “Hue”, “Ptn No”, etc. displayed on the lower side of the GUI screen in FIG. After pressing this icon, a pop-up screen with a numeric keypad is displayed.

  However, as another example, a unique item number is assigned to each setting item such as the brightness, saturation, hue, and effect pattern of the boundary line, and a numeric keypad is displayed on the GUI screen in advance. Specify the setting item you want to initialize by entering the item number using the numeric keypad. (If an item number is entered for an item that has an initial value in the parameter, click the “Default Recall” button near the numeric keypad. If the item number for an item for which no initial value exists in the parameter is input, the “Default Recall” button may not be displayed). As a result, the numeric keypad for inputting parameters can also be used as means for designating a setting item to be initialized.

  In the above example, when the “Default Recall” button 22 is pressed on the pop-up screen of FIG. 9, this pop-up screen is closed.

  However, as another example, the operation by the “Default Recall” button 22 may be as follows. When the “Default Recall” button 22 is pressed, the parameter is not immediately returned to the initial value, but the initial value is displayed in the display field 23 in the pop-up screen of the numeric keypad. If the Enter button is pressed, the value is confirmed, that is, the parameter is set to the initial value. On the other hand, if the Close button 24 is pressed, the pop-up screen is terminated without doing anything without setting the initial value. According to this embodiment, after confirming the content of the initial value on the pop-up screen, it can be determined whether it really applies. In particular, when the user sets an initial value, it is useful that the value can be confirmed before application.

  In the above example, the present invention is applied to a switcher. However, the present invention is applicable to any business application that is provided with a GUI and is controlled using parameters for a plurality of setting items including items having initial values. It can be applied to consumer electronic devices. Further, the present invention can be applied to all business / consumer electronic devices controlled using parameters for a plurality of setting items in which items having initial values and items not existing exist.
